By default, YASim will fix the neutral trim point to the specified
cruise conditions. If the actual wheel in the aircraft is not at
neutral/zero trim under those conditions, it will appear to be off.
You can add a property setting in the <cruise> section to correct
this. If the real aircraft would have the wheel at, say, 30% nose
down at cruise speed (with 50% fuel, which YASim currently hardcodes
as "cruise weight") you can add:
<cruise ...>
...
<control-setting axis="/controls/elevator-trim" value="0.3"/>
</cruise>
